Past participle is referred to action that has happened before and that has been completed from the time now.
The helping verbs that are used for past participle are have and had.
I wish I had met yesterday .
The option "C" is the correct one as had is the helping verb used for past tense . The word yesterday is time reference for past . Hence , option "C" is the correct choice .
The options "A" , " D" refer to present tense which don't satisfy the time frame yesterday mentioned in the sentence hence it is not the correct option .
"Would meet " refers to time frame in the future which does not satisfy the time frame mentioned in the sentence . Hence it is the wrong option.
